Dynamic channels are valid for this request. A channel value of zero is valid.

NUM_EC_POINT_DESC defines the number of descriptors within the DPD_EC_LDCTX_kP_ULCTX_GROUP

that use this request.

DPD_EC_LDCTX_kP_ULCTX_GROUP (0x5800) defines the group for all descriptors within this request.

Table 40. ECC_POINT_REQ Valid Descriptors (opId)

Descriptors Value Function Description

DPD_EC_FP_AFF_LDCTX_kP_ULCTX 0x5800 Load context in a dynamic channel to using an

electronic codebook for the FP AFF then get the

resulting P multiplier context

DPD_EC_FP_PROJ_LDCTX_kP_ULCTX 0x5801 Load context in a dynamic channel to using an

electronic codebook for the FP project then get the

resulting P multiplier context

DPD_EC_F2M_AFF_LDCTX_kP_ULCT 0x5802 Load context in a dynamic channel to using an

electronic codebook for the F2M AFF then get the

resulting P multiplier context

DPD_EC_F2M_PROJ_LDCTX_kP_ULCTX 0x5803 Load context in a dynamic channel to using an

electronic codebook for the F2M project then get the

resulting P multiplier context

DPD_EC_FP_LDCTX_ADD_ULCT 0x5804 Load context in a dynamic channel to using an

electronic codebook for the FP then get the resulting

context from an add operation

DPD_EC_FP_LDCTX_DOUBLE_ULCTX 0x5805 Load context in a dynamic channel to using an

electronic codebook for the FP then get the resulting

context from a double operation
